Bitcoin Core advances towards the elimination of the op_return limit and unleashes debates

By Canuto

The decision of Bitcoin Core developers to eliminate the historical limit of 80 bytes for Op_return has triggered an intense debate about transparency and the risks of spam in the Bitcoin network.

***

• Bitcoin Core developers decide to eliminate the limit of 80 bytes in Op_return.
• They argue that the measure will favor the transparency and coherence of the Bitcoin Network.
• Key figures such as Greg Sanders support change, while critics like Luke Dashjr criticize him.
• Those who oppose warn of potential spam increase and deviation of the financial approach.
• The decision is promoting alternatives such as Bitcoin Knots, which gives greater control to nodes.

The developers of Bitcoin Corethe nodes software Bitcoin More popular worldwide, announced the decision to completely eliminate the historical limit of 80 bytes in Op_return.

The decision means that from next version of Bitcoin Corethe bytes limit for the data embedded in Op_return will be, by default, higher, leaving behind an approach that previously restricted the data incorporated into the transactions of Bitcoin.

This change has unleashed a debate in the community of Bitcoinerswith critics warning that the measure will allow spam circulation in the world’s largest and oldest block chain.

What is op_return and why does your limit matter?

For those who enter the Universe BitcoinOp_return is a special field within transactions that allows you to insert non -monetary data visibly into the Blockchainwithout inflating the unbounded transaction output set (UTXO). Since 2014, the main protocol sets a top of 80 bytes to curb arbitrary storage, avoid unnecessary congestion and costs on the network.

This limit has been crucial to maintain the efficiency of the block chain and prevent abuse, while allowing legitimate use cases, such as time marks or cryptographic commitments. This has allowed Bitcoin He focuses on his financial mission, restricting those who seek to store information outside the network transactions.

However, the debate on its usefulness and validity has gained new strength with the proposal to eliminate this limit.

Massive inscriptions and advances in alternative storage methods have led to rethinking whether the restriction still protects the network or simply encourages more opaque pathways, compromising transparency.

The argument of the defenders

As reported COINDESKthe main defender of change is Greg Sanders (known online as ‘Instagibbs’), an engineer in Blockstream and prominent collaborator of the project.

Sanders argues that the limit does not fulfill its function, as users have found ways to enter large amounts of data using alternate paths, often creating incentives to manipulate false public keys or spending scripts. Eliminate the limit, argues, will allow a more predictable and safe behavior on the network, while cleaning the UTXO set —The registration of unbalanced balances – by avoiding deceptive transactions.

In his words, “Large data inscriptions are occurring anyway and can be done in more or less abusive ways. The limit simply channels them towards more opaque forms that damage the network”

The change, according to Sanders, aligns the ethics of Bitcoin Towards a model of “Minimum rules“Appealing to transparency; also, she is confident that the rates market will decide how the space available in the blocks is used.

Greater transparency or door open to spam?

Not everyone shares the optimism of developers of Bitcoin Core.

Luke Dashjr, an influential developer, argues that the measure could increase spam, promote the use of the network for extra-financial purposes and complicate the verification of transactions. Dashjr previously described the plan as a “Total madness”

Github discussions reflect ideological tension. Comments like “This marks a fundamental change in the Bitcoin direction” either “This is the biggest mistake that Core can make at this time, I want to record that”, Evidence growing polarization between the desire for innovation and the attachment to the original vision focused on the monetary functions of the network.

The debate in the community includes warnings of opinion leaders such as Samson Mow, CEO of Jan3 and ex cso of Blockstreamwho urged node operators not to update their software from Bitcoin Core in protest, or migrate to Knots.

“Bitcoin Core has announced that they will eliminate Op_return limit in its next version. Many users find this an undesirable change for several reasons. You can refuse to update and stay in version 29.0 or use another implementation like @bitcoinknots”Mow wrote on social networks.

Also the team of Bitcoin Mechanicpart of Ocean Miningand the founder of HomeJameson Lopp, have participated in the debate. Both parties have supported and rejected the measure citing the case of Citrea and his alleged need for no limits in Op_return. LOPP has refuted that argument saying that Citrea “Not even use op_returns for regular operations“

Bitcoin Knots are popular as an alternative

Bitcoin Knotsa bifurcation of Bitcoin Core Oriented to users who want more control over what their nodes accept or replicate, has gained traction in the middle of the debate, with approximately 5% of all nodes of Bitcoin adding to this alternative after the announcement of the changes. Dashjr, who has been critical of non -monetary inscriptions and transactions, leads that project.

Compared, Bitcoin Core It remains the implementation of Bitcoin More used, reaching 20,213 nodes, which represents 94.78% of the total attainable nodes in the network.

From the technical background, this change could have consequences in the daily operation and the policies of the nodes. By eliminating op_return limitation, some fear an increase in data volume and greater risk of congestion or costs for those who maintain nodes of the network, since they could now receive and replicate more information of doubtful utility.

On the other hand, the existence of alternatives such as Bitcoin Knots shows that decentralization offers options.

The story will continue …

In conclusion, the elimination of the limit to op_return marks a milestone in the technical and ethical evolution of Bitcoinalthough not necessarily in a unique sense. On the one hand, it expands transparency and reduces incentives for opaque practices; On the other, it worries those who see a dangerous turn towards the abuse of the network and the deviation of their original purpose.

What is clear is that the debate is far from being resolved and that both developers, as operators of nodes and opinion leaders, will maintain attentive observation about the consequences of this change in the short and medium term.
